Design and Performance
Flow Vector Control for High Performance Without Encoder
Operating in Open Loop Flow Vector Control (RFC) mode, the SP1402 controls magnetizing and active current separately, calculating rotor speed and position without requiring speed feedback, delivering very high performance for the majority of standard asynchronous motor applications.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP1402 remains actively sourced new, refurbished, and via repair-exchange programs for maintenance and like-for-like replacement, avoiding the complications of a full drive system retrofit.
Flexible Feedback and Communication Options
Supporting both incremental and absolute encoder feedback alongside RS-485/Modbus RTU communication, this drive adapts to a broad range of legacy control architectures requiring closed-loop precision or serial network integration.
High Output Frequency for Specialized Applications
With an output frequency range reaching up to 550 Hz, this drive supports specialized high-speed motor applications beyond standard 50/60 Hz industrial motor control.
Consistent Platform Across the Unidrive SP Range
Sharing the same flexible control interface and software parameters as other Unidrive SP sizes (from the compact SP0202 up to high-power SP5402 units), the SP1402 lets engineers standardize commissioning knowledge across projects using multiple drive frame sizes.
